How to set retention period for a delta table lower than the default period? Is it even possible?

manasa

I am trying to set retention period for a delta by using following commands.

deltaTable = DeltaTable.forPath(spark,delta_path)

spark.conf.set("spark.databricks.delta.retentionDurationCheck.enabled", "false")

deltaTable.logRetentionDuration = "interval 1 days"

deltaTable.deletedFileRetentionDuration = "interval 1 days"

These commands are not working for me, I mean, they aren't removing any files for the given interval..where am I going wrong?

There are two ways:

1) Please set in cluster (Clusters -> edit -> Spark -> Spark config):

spark.databricks.delta.retentionDurationCheck.enabled false

2) or just before DeltaTable.forPath set (I think you need to change order in your code):

spark.conf.set("spark.databricks.delta.retentionDurationCheck.enabled", "false")
